Here is a note from the management on how the run up to the event has been:

First rehearsal with choir and orchestra in St Paul the Apostle late last night. lots of teething problems. Sounds completely different when you take it out of a tiny rehearsal room. Not aided by fact that, being church, everything has to be broken down for mass now and again. I guess if they weren’t stressed they wouldn’t be human. Got a feeling it’s going to come together today. it’d better!
